Filter pivot for "Does Not Contain" to filter out 4 Character Strings

I have a huge pivot. In my "Description" column I have thousands of entries like "5CIG", or "EFTR", of "5168". Is there a way to configure the "Does Not Contain" filter to filter out if description is only a 4 character string? I'm open to either a VBA or non VBA solution.

Sorry it took me so long to get back. I tried the trick of using "not between" and start/end values of ????, and it appears to work. I also tried "Contains", using ?????*. I thought 4 question marks and an asterisk would mean "5 characters or more", but that left the 4 character strings present.

thanks for showing me another way around this. I'll have to do a comparison of the data sets to determine if one solution is more right than the other. "Appears" and "Is" can be worlds apart.

That's an important distinction. For this instance, I really want to get rid of anything 4 characters or less, but being able to get rid of ONLY 4 character strings can be hugely helpful. Thanks for showing me the way.
